Replacing and Calibrating Thinkpad Battery?

Ey guys, I just got a new battery for my T60 and I was wondering if I need to fully charge it before using it. Also, how should I go about calibrating it to ensure better battery life? Should I first fully charge it then drain, then charge again? Thanks in advance!

Thanks for the response man. But if I set my Thinkpad to not charge until below 85% for example, won't it not charge when turned off, even if the AC adapter is still connected to it? I am thinking of testing it out, but please let me know if any one knows the answer to this. Thanks!

How can I set my battery charge level to 90%? Currently, my battery is charging to 100%. Will the charging of the battery continue even after it has been charged fully when connected to AC? Is the answer to the previous question true for both when the computer is ON and OFF?
Thank You

I have attached a screenshot so you can see how to set your charge level limit to i.e. 90%. In the example shown, I have set it to start charging when below 60% and stop charging at 90%. You will find the page under Power Manager > Battery Information > Battery Maintenance.

As for your other question. The battery cannot be overcharged and destroyed (as you wrote in a different post). There is a mechanism which prevents this. Li-Ion laptop batteries have built-in controller chips which prevent them from overcharging.

Here's a guide which I think you will find useful. There are many opinions about this matter, but I find the information in the guide to be quite valid.

As for calibration/Battery gauge reset, I personally set ThinkVantage Power Manager to notify me when a reset is recommended. In case you don't know where to find it, you can see the ticker box in the screenshot I attached to the previous post.

Wow, thanks for the info Jabba! I was looking for a guide like that! So I am going to calibrate my new battery right now... going o charge it to full... run it down, then charge it again. Let me know if there is anything else you think I should do.
Thanks.

Well, I just popped in the battery and went to the power manager to view the battery details and noticed that the manufacturing date is 5-24-07, and I just got it last week from NewEgg.com. The battery is pretty much 6 months old and I just got it... Do you guys think I should try to get a replacement? Thanks.
